IMPROVEMENT IN GUARDS FOR LANTRNS.

Specification forming part of Letters Patent No. 34,447, dated February18, 1862.

To a/ZZ whom it may concern:

Be it known that I, WILLIAM l-I. PIERCE, of East Cambridge, in thecounty of Middlesex and State of Massachusetts, have invented anImprovement in Guards for Lanterns; and I do hereby declare the same tobe fully described in the following specification and represented in theaccompanying drawings, of which- Figure l is an eleva-tion of alanternhaving a guard applied to it in accordance with my invention; Fig. 2, atop view of the guard and ring; Fig. 3, an elevation of one of thesections of the guard; Fig. 4, a top view of' the same; Fig. 5, 'a topview of the circumscribing ring.

rlhe nature of my invention consists in an improved mode of securing aguard to a lantern, whereby the said guard can be either readily appliedto the lantern or detached therefrom, as circumstances may require.

In constructing the said guard I make it in two parts or sections, oneof such sections being shown in Fig. 3. The rims A B of the guard areeach made in two parts a a b b. The ends of the upperand lower portionsmay be respectively made to abut against each other; but I prefer tohave one lap on the other, and to have a small stud formed on each ofthe underlying ends, as seen in Fig. 4, to extend (when the guard is inplace on the lantern) into or through corresponding holes formed in theoverlapping ends. From the two portions ct ct of the rim A a series ofcurved wires or ribs o 0 o o', &c.,are attached and extended downwardand are affixed to the rim B, as seen in Figs. l and 3. Each of theseribs is curved outward, but has an inward bend or curve c near itscentral part, which gives to it in side elevation a double curve, asseen in the drawings. Around these series of ribs and transversely ofthe same a circumscribing annulus or inclosing-band C is to be placed inorder to conne the guard to the lantern. This band may be either of acircular, hexagonal, or any other proper form; but I prefer to constructas shown in Fig. -that is, of a hexagonal form-and with each of itscorners curved or made of a semispherical shape, so that when such bandis placed upon the ribs and forced down into the depressions c such bandshall remain firmly fixed in position and serve to support or strengthensuch ribs, and, moreover, the said band should be of such diameter as toslightly bear on the outer surface of each of the ribs at the point cofits intersection when such band is applied to the ribs, as shown inFigs. l, 2, and 3. By this peculiar construction of the band or ring Cand the ribs o o', when the said band is pressed down over the said ribsand into the notches or depressions c the two become so connected as toform a sort of a lock.

In operating with my improvement the two rims of the guard are to beapplied to the small parts of the lantern above and belowr the swells ofthe glass. Next the band or ring C is to be forced down over the seriesof Vertical ribs into the depressed portions c,

when the guard will be firmly locked to the purpose set forth.
